RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No.15/006,890, filed Jan. 26, 2016 (U.S. Pat. No. 10,648,168), which claimsthe benefit of U.S. Provisional Application Ser. No. 62/107,925, filedJan. 26, 2015, the entire teachings of which are incorporated herein byreference.

BACKGROUND OF THE INVENTION

Shelter, food, water and clothing represent key human needs that arenecessary to satisfy long-term physical well-being and survival.Providing basic shelter may be particularly difficult in impoverishedregions or in response to a crisis situation, for example, in responseto natural or man-made disasters or in relation to relief efforts.

While temporary shelter systems have been developed to facilitateresponses to disaster relief efforts, such shelters may be difficult andtime-consuming to assemble or deploy. Moreover, depending on theenvironment into which such shelters are to be deployed, the lack ofelectricity, tools and other resources may present specific challengesto an intended user that can dramatically limit the overall utility ofsuch shelters.

Given the extreme conditions to which humans may be exposed during orimmediately following a disaster event, it remains critical to quicklyand efficiently fulfill the basic human need for shelter. Needed aretemporary shelter structures and systems that fulfill the basic humanneed for shelter and that preferably provide a safe, secure andsemi-permanent shelter structure to individuals in need thereof.Particularly needed are temporary shelter structures and systems thatare capable of being quickly and easily deployed in response to, forexample, a natural disaster event. In view of the harsh environmentsinto which such shelter structures may be frequently deployed, such asfor example, war zones or in connection with disaster relief efforts,also needed are shelters and shelter systems that lend themselves toeasy assembly and disassembly.

DETAILED DESCRIPTION OF THE INVENTION

Conventional portable shelters take a considerable amount of time,personnel and effort to assemble and deploy, which presents particularchallenges when such shelters are intended for deployment under lessthan ideal circumstances. Accordingly, deployment speed and simplicityrepresent valuable characteristics of temporary shelters and sheltersystems.

The shelters and shelter systems disclosed herein are versatile and, forexample, may be configured for use and deployment in virtually anyconditions, climates or environments, thereby making them well-suitedfor deployment in response to a variety of events, such as in connectionwith disaster relief efforts or in active combat zones. Disclosed hereinare shelters and shelter systems (e.g., temporary modular shelters) thatare configured for easy shipment and straightforward assembly. Incertain aspects, the shelters and shelter systems described herein maybe quickly and easily assembled without the use of special tools orskilled labor, making them particularly well-suited for use inconnection with, for example disaster relief efforts, where specialtooling may not be readily accessible.

The assembled shelters disclosed herein are durable and are able towithstand exposure to harsh environmental conditions and terrains yet,in certain embodiments are specifically configured for temporary use,following which such shelters may be easily disassembled and redeployed,as needed. As depicted in FIG. 1, the shelter systems disclosed hereinare configurable into a stowed configuration, making them well-suitedfor shipment. In certain embodiments, the shelters disclosed herein maybe disassembled (e.g., disassembled without the use of tools or otherspecialized equipment). For example, when use of the shelter is nolonger required, such shelters may be easily disassembled, thecomponents of the shelter stowed in a secure container structure such asthat shown in FIG. 1, and the stowed shelter may then be easilytransported and/or deployed to another location.

As illustrated in FIG. 1 and in FIGS. 6A-6D, the container of theshelter system houses all of the components needed to assemble theshelter and such container is formed by a plurality of rigid floorpanels, which are ultimately assembled to form the floor of the shelter.For example, as illustrated in FIGS. 2A-2D and in FIGS. 6A-6D, thecomponents of the stowed shelter systems disclosed herein are easilyassembled without the use of specialized tooling or equipment. Incertain embodiments, the components of the shelter system are stowed orotherwise packaged inside of the container (e.g., a crate formed by oneor more rigid floor panels) in the order of assembly of such components.Similarly, in certain embodiments, the components of the shelter systemmay be disassembled and packaged in reverse order of assembly of suchcomponents. For example, an assembled shelter system may be disassembledby following the assembly instructions depicted in FIGS. 6A-6D inreverse order.

In one aspect, the shelter systems disclosed herein comprise a pluralityof rigid floor panels and a plurality of rigid wall panels, each suchwall panel having a top end and a bottom end substantially parallel tothe top end, as depicted in FIG. 2B. The shelter systems disclosedherein may further comprise a plurality of rigid top caps, which incertain embodiments help to improve the stability of the shelter.

The roof of the shelters disclosed herein may be assembled usingcomponents of the shelter systems disclosed herein, such as a roofsupport structure (e.g., a roof support structure comprising a pluralityof rafters) and a roof structure (e.g., a flexible roof structure). Forexample, as depicted in FIG. 2C, FIG. 6C and FIG. 14A, the roof supportstructure of the shelter, which is formed using a plurality of rafters,may be coupled to the top end of the assembled walls. FIG. 2D, FIG. 6D,and FIG. 14B depict the assembled or deployed shelter, the roof of whichis formed by coupling (e.g., releasably coupling using snaps, hook andloop closures, or other similar means known to those of skill in theart) a vented fabric roof to the underlying roof support structure, andonto which a shade fly may be releasably attached. In those embodimentsin which the roof structure is a vented fabric roof, the hems of suchfabric roof may comprise one or more stiffeners to impart added strengthand durability to such fabric roof, for example, in those areas in whichsuch roof structure couples to the top end of the assembled walls. Suchstiffeners also serve to distribute the load of the roof across thefabric roof and promote a better seal of the fabric roof to the top endof the assembled walls. Alternatively, in certain embodiments, the roofstructure of the shelters may comprise one or more rigid roof panels,which can be coupled to the roof support structures disclosed herein. Incertain aspects, the roof support structure comprises a plurality ofrafters, as depicted, for example, in FIGS. 6C-6D. Such rafters may beprepared using, for example, wood, plywood, metal or thermoformedplastic. Such rafters may be flame resistant. In certain embodiments,such rafters each comprise a first end and a second end to which arecoupled a rafter supporting member capable of engaging or otherwisecoupling to the rigid top caps to thereby form a roof support structurecomprising series of rafters and onto which the roof structure may becoupled to form the roof of the shelter. For example, as depicted inFIGS. 4A-4D and in FIG. 6C, the rigid top caps may be configured toreleasably couple to the rafter supporting members to thereby define aroof support structure. As illustrated in FIG. 4C, in certainembodiments, upon coupling the rafter supporting members to the topcaps, the first and second ends of the rafters do not project beyond thewalls or the top caps (e.g., the first and second ends of the raftersupporting members do not extend or otherwise project beyond the outeredge of the top caps), which facilitates the securing of the rafter inits vertical position and the coupling of the roof structure to theunderling roof support structure, while also promoting the formation ofa weather- or watertight seal, as shown in FIGS. 14A-14B. The assembledroof support structure may be configured to releasably couple to theroof structure to thereby form a roof of the shelter. In certainembodiments, the rafters may be folding, telescopic or retractable, forexample, to reduce their size and thereby improve their portability(e.g., in a stowed configuration). In those configurations where therafters are folding, telescopic or retractable, such rafters may furthercomprise a stabilizing means (e.g., a lock) to stabilize the rafters andthe roof support structure. In certain embodiments, the roof structureand/or the assembled roof of the shelter is thermally insulated.

The floor of the shelters disclosed herein may be assembled using aplurality of rigid floor panels that form the container of the sheltersystem, for example, as illustrated in FIG. 2A and in FIGS. 6A-6B. Thus,in certain aspects, the floor of the shelter is formed by assembling oneor more rigid floor panels, which may be configured or assembled into afolded state and a deployed state. In certain embodiments, one or moreof the rigid floor panels are interconnected to each other. In certainembodiments, the rigid floor panels are hollow. For example, rigid floorpanels may comprise or be prepared with insulated core floor or with afully enclosed plastic panel. One or more extrusions may then be affixedto or otherwise formed on one or more edges of such floor panels, forexample, to facilitate the coupling (e.g., releasably coupling) of suchfloor panels to one or more wall panels.

In certain embodiments, the floor panels included in the shelter systemsdisclosed herein serve multiple (e.g., dual) purposes. For example, asdepicted in FIGS. 6A-6B, in the folded state the rigid floor panels maybe assembled to form a container that is configured to securely housethe components that comprise the shelter system in a stowedconfiguration. Conversely, in the deployed state the floor panels may beassembled to form the floor of the shelter.

In certain embodiments, one or more of such floor panels may beinterconnected to each other (e.g., using a hinge), such that thecontainer formed by such floor panels may be easily deployed to form thefloor of the shelter. For example, in certain embodiments, a rigid floorpanel may form a removable lid of the container while the remainingfloor panels may be interconnected such that they can be easily deployed(e.g., unfolded or assembled) to form a portion of the shelter's floor.In such embodiment, the floor panel forming the lid of the shelter canbe releasably coupled to the deployed (e.g., unfolded or assembled)interconnected floor panels, thereby forming the assembled floor of theshelter.

In some embodiments, the floor of the shelter (e.g., the floor formed byassembling a plurality of rigid floor panels) defines a perimeter of ashelter (e.g., a rectangular perimeter), as depicted in FIGS. 6A-6B. Insome embodiments, the perimeter of the shelter comprises an extrusionconfigured to releasably accept or couple to the bottom end of one ormore wall panels. As depicted in FIG. 2B, to construct the walls of theshelter, a plurality of wall panels are releasably coupled to theextrusion that is configured to perpendicularly and releasably couple tothe bottom end of the rigid wall panels. Such extrusions may furthercomprise one or more spring clips that allow the wall panels to becoupled to the perimeter of the floor in a releasable manner.

In certain aspects the extrusions may be configured as an integratedextrusion that may be used to form a joint system to couple the wallpanels and/or floor panels to each other, as depicted in FIGS. 7A-7C.Such an integrated extrusion may be particularly useful in thosesettings in which enhanced thermal performance of the shelter is desired(e.g., in arctic or polar regions). For example, such an integratedextrusion may be formed, molded or otherwise configured to mate with orotherwise engage a thermoformed tongue that may be formed on one or moresides, edges or ends of an adjacent wall panel and/or floor panel.Accordingly, in certain aspects, the side, edge or end of such a wallpanel and/or floor panel may be formed as a groove that comprises or isintegrated with the extrusion and that is configured to be accepted orotherwise mate with a thermoformed tongue extrusion that is formed on orin an adjacent wall panel or floor panel, as depicted in FIGS. 7B and7C. Such integrated extrusions therefore may be connected with anadjacent wall panel and/or floor panel, thereby forming a weather-and/or air-tight seal.

Integrating the extrusions into the sides or edges of a panel (e.g., awall and/or floor panel) advantageously lowers the profile and weight ofsuch panel, thereby forming a seamless, weather- and/or air-tight sealwith little thermal bridging. In certain aspects, the integratedextrusions are formed using the same material as the panel. In certainembodiments, the integrated extrusion may be formed of polyvinylchloride (PVC). In yet other embodiments, the integrated extrusion maybe co-extruded with pliable fins, as depicted in FIG. 7A, to improve theseal between the integrated extrusion and an adjacent panel (e.g., toform air-tight seal between two adjacent panels). In certain aspects,the integrated extrusions disclosed herein may be configured to coupletwo adjacent panels to form an angle. For example, two wall panels maybe connected at a ninety degree angle relative to each other, asdepicted in FIGS. 8A-8C, to form the corners of the shelter system. Asshown in FIGS. 8A and 8B, a corner extrusion may be formed and/orintegrated in the panel and configured to be coupled to the extrudedgroove formed or integrated on an adjacent panel, thereby forming aninety degree corner. FIG. 8C illustrates the integrated extrusionforming a corner using two adjacent wall panels that are releasablycoupled to each other at a ninety degree angle.

It should be understood that, as used herein, the term “releasably”means that the respective members (e.g., an extrusion and one or morerigid wall panels) may be securely attached to each other and detachedfrom each other repeatedly without damage to the members. This may beaccomplished, for example, by using the extrusions which comprise springclip connections or with use of the rigid top caps disclosed herein, asshown in FIGS. 4A-D. Similarly, in certain embodiments the respectivemembers may be securely attached to each other and subsequently detachedfrom each other (e.g., by using the extrusions which comprise springclip connections or with use of the rigid top caps disclosed herein)repeatedly without the use of tools. In certain embodiments, once thewalls of the shelter have been assembled (e.g., by releasably coupling aplurality of wall panels to extrusions located on the perimeter of thefloor), such walls may be further stabilized or braced using, forexample, a plurality of rigid top caps, for example as illustrated inFIG. 6C. In certain embodiments, the top ends of the rigid wall panelsare configured to releasably couple to the rigid top caps, asillustrated in FIGS. 4A-D. In certain embodiments, the rigid wall panelsare hollow. For example, rigid wall panels may comprise or be preparedwith hollow core floor. In certain embodiments, one or more extrusionsmay be affixed to or otherwise formed on one or more edges of such wallpanels, for example, to facilitate the coupling (e.g., releasablycoupling) of such wall panels to one or more floor panels or to one ormore top caps.

In certain embodiments, the shelters disclosed herein are modularshelters. Such shelters comprise a plurality of walls (e.g., four ormore walls), each of which may further comprise a plurality of rigidwall panels having a top end and a bottom end substantially parallel tothe top end. The shelters disclosed herein may further comprise aplurality of rigid top caps. In some aspects, the rigid top caps may beconfigured to releasably couple to the top end of the rigid wall panelsand to thereby stabilize the walls of the shelter (e.g., by releasablycoupling a rigid top cap to the top end of two or more adjacent wallpanels).

In certain embodiments, the shelters may be thermally insulated, therebymaking the shelter suitable for deployment in diverse environmentalconditions. For example, in some aspects, one or more of the pluralityof the floor panels may be thermally insulated. Similarly, in otheraspects, one or more of the plurality of wall panels may also bethermally insulated. In certain embodiments, such floor panels and/orwall panels are insulated with radiant barrier films. In someembodiments, such radiant barrier films incorporate an air space on eachside of the radiant barrier film.

In certain embodiments, the shelter systems comprise two or more walls(e.g., two, three, four, five, six or more walls). In certainembodiments, such walls may be configured to be substantially parallelto each other (e.g., the front wall may be configured to besubstantially parallel to the rear wall and/or two side walls may beconfigured to be substantially parallel to each other). In certainaspects, one or more of the wall panels that comprise the wall of theshelter may comprise one or more windows. In certain aspects, one ormore of the wall panels that comprise the wall of the shelter maycomprise one or more doors, as illustrated in FIG. 2B. Such doors orwindows may be incorporated into the molds that are used to form thewall panels.

One aspect of the shelters and shelter systems disclosed herein is thattwo or more assembled or deployed shelters may be releasably coupled toeach other in any desired combination or configuration. Accordingly, insome embodiments, the shelters and shelter systems disclosed herein aremodular. In some aspects, one or more of the wall panels that comprisethe wall of the shelter may comprise one or more expandable connectorsthat may be configured to releasably connect one shelter structure to anadjacent shelter structure, thereby allowing multiple configurations ofsuch modular shelter systems. For example, in some embodiments, a firstshelter (e.g., a base unit) may be releasably connected to a second,third, fourth, fifth, sixth, seventh, eighth, ninth, tenth or moreshelter (e.g., a shower unit, latrine unit, a second base unit), therebyforming a complete living unit. Similarly, a series of assembledshelters (e.g., two, three, four, five, six, seven, eight, nine, ten ormore assembled shelters) may be deployed and connected together to forma desired combination so that, by way of example, one shelter may serveas a living quarter and be releasably coupled to an adjacent shelterthat is configured as a kitchen, mess hall or a latrine. In certainembodiments, a single wall panel may comprise an expandable connector.Alternatively, in those embodiments where, for example, a widerconnection between two shelters is necessary (e.g., to facilitatepassage of a gurney between two adjacent shelters), two or more walladjacent panels may comprise an expandable connector (e.g., two, three,four or more adjacent wall panels that comprise the assembled wall ofthe shelter may comprise an expandable connector). In certainembodiments, the expandable connectors may further comprise a rigidfloor panel to thereby form a hallway or corridor that connects twoshelters to one another, for example, as depicted in FIGS. 5A-5C. Incertain embodiments, the expandable connector is thermally insulated.

The shelters and shelter systems disclosed herein may further comprisemeans to secure the shelter and its contents. For example, in thoseembodiments where the shelter comprises a door or a window, one or moreof such doors and windows may comprise a lock.

The shelters and shelter systems disclosed herein are configured to beraised off of the ground in an assembled or deployed configuration,thereby keeping the floor of the shelter away from insects, vermin andminor flooding. In such embodiments, the underside of the rigid floorpanels may comprise one or more footings or supporting members, forexample as illustrated in FIG. 2A and in FIG. 6A, that serve to elevatethe shelter structure off of the ground. In certain embodiments, suchfootings are adjustable and accordingly may be used to customize theheight of the shelter. In certain embodiments, such adjustable footingsprovide a means of leveling the shelter if the ground onto which it isplaced is not entirely flat. In other embodiments, such footings areattached to the floor panels that form the container of the shelter inits stowed configuration and serve to hold such container off of theground, for example, to facilitate shipment and/or storage of suchcontainer (e.g., in lieu of affixing a standard shipping pallet to theunderside of such container, one or more footings may be attached to thefloor panels forming the underside of such container).

In certain embodiments, the assembled roof of the shelter stabilizes theshelter (e.g., stabilizes the walls of the shelter). As shown in FIG. 3,in certain embodiments, the roof of the shelter is curved orbarrel-shaped, which advantageously facilitates the elimination ofprecipitation from the interior of the shelter. The shelters and sheltersystems disclosed herein may also comprise one or more cam straps tofurther stabilize the assembled shelters or the components of theshelter system. For example, one or more cam straps may be used tosecure the roof to the walls of the shelter.

As shown in FIG. 2D and FIG. 3, the shelters and shelter systemsdisclosed herein may further comprise a shade fly, which may be affixedto the roof of the shelter. In certain embodiments, the shade fly is asolar shade fly and provides passive cooling and shade to the shelter.

In certain embodiments, the shelters disclosed herein may furthercomprise one or more ground anchors.

The shelters disclosed herein are characterized by the ease with whichthey can be assembled and disassembled. In certain aspects, the sheltersdisclosed herein may be assembled or disassembled without tools. Incertain embodiments, the shelter systems disclosed herein may beconfigured as a kit, which further comprises assembly instructions(e.g., instructions that graphically depict the assembly of the shelter,as shown in FIGS. 6A-6D). In certain embodiments, such assemblyinstructions may be followed in reverse order to disassemble theassembled shelter system.

The shelters and shelter systems disclosed herein may be configured fordeployment in any environments or climates. For example, as discussedabove, such shelters and shelter systems may be configured with a shadefly to provide passive cooling to an assembled shelter that is intendedfor deployment in a desert or tropical climate. Conversely, in certainaspects the shelters and shelter systems disclosed herein may beconfigured for deployment in cold or arctic environments or climates.For example, one or more components of such shelters and shelter systems(e.g., a floor panel, a wall panel and/or the roof structure) may beinsulated to retain heat in the assembled shelter or to minimize heatloss.

The shelters and the components thereof may be insulated with any numberof materials, which in certain embodiments, may include radiant films orbarriers, conductive insulation barriers or materials and anycombinations thereof. For example, in certain aspects, the shelters andany components thereof may be insulated using a composite insulatingmaterial that comprises a reflective insulating material (e.g., aradiant film or barrier), onto which may be disposed or otherwiselayered a conductive insulating material (e.g., one or more foamconductive insulation barriers or layers). The use of such compositeinsulating materials provides a means of improving the thermalperformance of the shelter system and its components, for example,relative to the individual reflective insulating material or theconductive insulating material. Additionally, the inclusion of both areflective and a conductive insulating material or barrier as componentsof such composite insulating materials may be used to limit or eliminatephysical contact with the underlying radiant film or barrier and, as aresult, heat cannot be transferred through conduction and all heattransfer must be radiant. Accordingly, in certain aspects, the compositeinsulating materials disclosed herein comprise a space on each side ofthe reflective insulating material (e.g., a physical space or gaplocated between the reflective insulating material and the conductiveinsulating material). In certain embodiments, the reflective insulatingmaterial (e.g., radiant barriers and films) that comprise the compositeinsulating materials disclosed herein are up to 95% effective atreflecting radiated heat. This translates into a greatly reduced load.

As used herein, the term “load” refers to the amount of work themechanical heating or cooling systems must do to reach and/or maintain aset interior temperature. The composite insulating materials disclosedherein trap heat within the shelter or bounce it away, thereby reducingload. For example, in certain embodiments, the composite insulatingmaterials disclosed herein are able to reduce load by about 10%, 20%,25%, 30%, 40%, 50%, 60%, 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99% ormore. When the shelters and shelter systems disclosed herein aredeployed to a cold or arctic environment, the inward-facing radiantfilms or barriers help to trap heat in the shelter, thereby reducingload.

The composite insulating materials disclosed herein may beadvantageously configured to also keep heat out of the assembled shelterby configuring such composite insulating materials such that thereflective insulating material (e.g., radiant barriers) are directed orotherwise point towards the exterior of the shelter. For example, incertain aspects, a composite insulating material may be deployed in oron the shelter or on any of its components (e.g., a wall panel, a floorpanel and/or roof structure) such that the radiant barrier reflects heatoutward, thereby reducing the temperature inside the assembled shelter.

As depicted in FIG. 9, the roof structure of the shelter system maycomprise a composite insulating material. In certain embodiments, theroof or roof structure is or comprises a three-layer compositeinsulating material consisting of or comprising a reflective insulatingmaterial (e.g., a radiant film or barrier), disposed onto a conductiveinsulating material (e.g., THINSULATE G100), and having a heavy duty,weather resistant exterior layer. Such a composite insulated roof orroof structure may be installed in the same way as the standardsingle-ply roof structure discussed above, but with additional tie-downsand reinforcing. The insulated roof structure completes the shelterassembly and the exterior envelope, and is part of the enclosed airspace above the ceiling, as depicted in FIG. 10. As shown in FIG. 9, anexemplary insulated roof may be formed as a composite material andcomprises a downward-facing thermal reflective insulating roof structurelayer (e.g., a radiant barrier manufactured by Brookwood), a conductiveinsulation material or layer (e.g., THINSULATE G100) and an exterior 600denier coated polyester material (Kenyon).

The assembled shelter may comprise an insulated ceiling, which incertain embodiments comprises a composite insulating material, asdepicted in FIG. 11. In certain embodiments, the insulated ceilingcomprises a multi-layer composite material consisting of or comprising areflective insulating material (e.g., one or more radiant films orbarriers) onto which is disposed a conductive insulation material (e.g.,a water-resistant insulating material, such as THINSULATE G100). Uponassembly of the shelter, the insulated ceiling may be installed from theprotected interior of the assembled shelter by attaching or fixing suchinsulated ceiling to undersides of the rafters, forming an enclosed airspace between the ceiling and the roof components, as depicted in FIG.10. As shown in FIG. 10, the air space between the rafters provides animportant sealed space between the two insulating components (e.g., theinsulated roof and the insulated ceiling), thereby increasing overallthermal performance of the assembled shelter. An exemplary insulatedceiling is depicted in FIG. 11 and comprises a downward-facing thermalreflective layer (1) that is a metallized radiant barrier rip stop nyloncloth, onto which is disposed a conductive insulation layer (2) (e.g.,THINSULATE G100). Advantageously, the insulated ceiling can be madereversible to function very well in hot climates.

In certain embodiments, the floor and/or floor panels of the sheltersystem may also be insulated, for example, by disposing a compositeinsulated floor mat on each floor panel or on the assembled floor of theshelters disclosed herein. Accordingly, in certain aspects, providedherein is an insulated floor and/or floor panel comprising a compositefloor mat that may be affixed (e.g., affixed using a hook and loopsystem) to the floor panels or to the floor of the assembled sheltersdisclosed herein. In certain aspects, the insulated floor mat comprisesa composite insulating blanket (e.g., a 5-ply composite material) thatmay be installed onto the floor panels that form the base of the sheltercontainer or crate. Upon assembly of the shelter, the insulatedcomposite floor mat may be unfolded and affixed or otherwise sealed ontothe floor of the assembled shelter by means of, for example, a hook andloop system that is located on or about the perimeter of the assembledshelter. An exemplary insulated composite floor mat is depicted in FIG.12. As shown in FIG. 12, the insulated composite floor mat comprises anupward-facing surface (1) which may be constructed, for example, of aheavy duty, NFPA 701 compliant commercial tent floor, and which may bedisposed onto a reflective insulation material (e.g., a radiant film orbarrier) core (2) (e.g., SKYTECH by Winco), that is disposed onto eachside of a high density e-glass filament blanket, and a scrim layer (3)to protect downward-facing reflective material.

Also contemplated herein are insulated wall and/or floor panels. Incertain embodiments, the thermally insulated wall and/or floor panelsmay also be formed of a rigid composite insulating material. Forexample, such thermally insulated composite panels may comprise areflective insulation material core (e.g., a bidirectional radiant filmor barrier core), onto which may be disposed a conductive insulatinglayer, and onto which a rigid exterior layer may be disposed, therebyforming the composite panel. In some embodiments, the compositeinsulating materials disclosed herein comprise a physical space or gaplocated between the reflective insulating material layer and theconductive insulating material layer. In certain aspects, the thermallyinsulated panels (e.g., a wall panel and/or a floor panel) comprise atleast five layers and include a bi-directional radiant barrier. As shownin FIG. 13, such thermally insulated panels may comprise abi-directional radiant barrier film (e.g., SUPER R PLUS by InnovativeInsulation) at the panel's core or centerline. Such radiant films orbarriers provide a means to trap heat in or to keep heat out of theshelter structure, depending upon the deployment conditions. In certainaspects, a conductive insulating material or layer (e.g., a machined EPSfoam layer) may be disposed onto the radiant barrier film to surround orsandwich the radiant barrier film, thereby providing conductive thermalinsulation and performing as a spacer. The two conductive insulatinglayers surround or sandwich the film, holding it in position between twoair spaces, keeping almost 90% of the surface area as a radiative heatsurface. A rigid exterior layer made of, for example, ABS-polycarbonatemay be disposed onto the interior and exterior surfaces of the panel toprotect the core insulating layers and to provide a weather tight sealand structural rigidity to the panel. In certain aspects, the resultingcomposite insulating panel is relatively thin in size (e.g., a width orthickness of about 100 mm, 90 mm, 80 mm, 70 mm, 60 mm, 50 mm, 45 mm, 40mm, 35 mm, 30 mm, 25 mm, 24 mm, 23.5 mm, 23 mm, 22 mm, 21 mm, 20 mm, 15mm, 10 mm, 5 mm, or less) compared to, for example, conventionalinsulated building materials.

It should be understood, that while certain aspects disclosed hereincontemplate the use of the thermally insulated building materials andpanels to form the floor panels or wall panels of the shelters andshelter systems disclosed herein, such thermally insulated buildingmaterials and panels may be useful for other purposes. Accordingly, alsodisclosed herein are thermally insulated composite building materials,as described in U.S. Provisional Application No. 62/287,231, filed onJan. 26, 2016 (Attorney Docket No. VBGD-003-001), the entire teachingsof which are incorporated herein by reference. In particular, suchthermally insulated building materials and panels may be used as astand-alone product due to it is relatively thin (e.g., about 23.5 mm)size, and at +/−R-15, such panels perform as well as materials that arefour to eight times as thick. In particular, such thermally insulatedbuilding materials and panels are useful in developing highly energyefficient sheathing for use in the conventional building industry. Asenergy costs continue to rise and building codes become more performanceintensive, the thermally insulated panels disclosed herein may be usedas an alternative or replacement for standard building materials, suchas plywood.
